ADHESIVE COMPOSITION.

Specification of Letters Patent.

No Drawing.

To all whom it may concerm.

Be it known that I, Mom;

R. IsAAcs,-a citizen oftheUnited' States, and a resi dent delphia, and State of Pennsylvania, have invented certainnew and useful Improvements in Adhesive Compositions, of which the following is a full, clear, and complete. disclosure.

The object of my invention is to produce.

an adhesive compound,'glue or sizing from suitable proteid, andcasein or any other lime or other suitable earth hydroxid, of

such a character that the composition in its original form is a dry powder or granular fluid containing all the different ingredients, andwill so remain suitable or satisfactory for use evenaiter exposure to either dry or moist air for a considerable period.

It has long been known that casein or other suitable -'proteids'mixed withlime or other being especially difierentiated from other casein adhesives by theirstrength and waterproof qualities. of the United States heretofore granted to me, such for instance. as U. S. Patent No. dated March 5, 1907, and No.

scribed certainmethods of improving such adhesive compositions by using certain other substances, *such. as sodium' flu orid and tion composed of Portland cement, in con able, by reason of the'fa 'unction with casein and lime. It is desirable, however,- to increase the permanence or chemical stability of these adhesive compositions, ,as well as that of the simple lime-casein composition, and it has been heretofore attempted to accomplish'this object in one-of two Ways, namely ;+(1) by keeping the casein or other proteid, anddesired toproduce the adhesive by mixing them with a suitable quantity of Water; and (2) by adding to the composicasein or other proteid and lime orotherhydroxid, a relatively large amount of an inert substance, stance as talc, clay, etc., such'amountbeing of casein or other proteid, and of lime or other similar hydroxld, fromfcoming 1n actual-contact with the two ways above described is objectionct that it necessithe impropermixing or of-Philaby reason of the produce excellent In various Letters, Patentlime or other hydroxid, in sep-' arate parcels or packages until the time when it is composition, such for 1n-.

tates se arate and gjes rise to those troubles incident to proportioning of .the ingredients in finally water and the erties of the finished product are impaired by i that by combining withthe composition composed of casein or other proteid, and lime or otherxsimilar packages of the ingredients,

second is also objectionable fact that the adhesive propforming the adv hesive composition by mixing the samein the inertmineralsubstances containedthereinlw .Ihave dlscovered, however,

hydroxid, a relatively small amount of cer-.

'tain organic substances,

after standing several months in open bags, and which willreadily mix with water and form an excellent adhesive even after such a ,acomposition may beobtamedWhiCh does not deteriorate even long time has elapsed. The organic substance which I have. found to be particularly effective and eflicient for the purpose isspirits of turpentine,but I do notwish to limit myself to this particular substance, inasmuch as other. terpene pine oil, oil of camphor. and similar liquids produce the desired result. By terpene xliquid I here, and in my-claims, mean any liquid, whether it be. a chemicalcompound or a mixture, that contains a terpene, or any analogous liquid which is obtained by the distillation of a resin or resinous .wood.

Theseterpene liquids can be used with animal-or vegetable proteids other than casein,

such for example as with hide or bone glue, i

and they may be used with good results with alkaline earth hydroxids other than lime, .such' for example as barium hydroxids,

both of the same with lime in the casein composition.

In carrying my invention into practice I' mix the turpentine or other terpene liquid with casein or other proteid, or I may mix theturpentine with the lime or other similiquids, such as 80 strontium hydroxids, or a mixture of one or lar hydroxid, or I may mix apart of the the result or results reduced to the form of a homogeneous powder or granulated matter (to accomplish which it will often be necessary after stirring or mixing by ma chine, to run the mixture through a sieve and then stir well, or run again through the mixer), the resulting composition will be 7 dry and homogeneous, and will form a glue or adhesive upon being mixed with the proper amount of Water.

The amount of turpentine or other terpene liquid used in said composition may vary within wide limits but there should never be used a sufficient quantity to make the I find with one twelve parts by Weight of lime, with or without sodium fluorid five parts by weight,

and with or without Portland cement ten parts by Weight, that from one quarter of one part to three quarters of one part by weight of spirits of turpentine or a similar amount of .pine oil, will give very satisfactory results, but I do not wish to limit myself to these exact proportions, inasmuch as theywill be varied considerably and still produce a satisfactory resulting combination.

Having thus described my invention, I claim and desire to protect by Letters Patent of the United States:

1. A composition of matter containing casein, an alkaline earth hydroxid, and a terpene liquid.

2. A composition of matter containing casein, lime, and a terpene liquid.

A composition of matter containing casein, lime, and spirits of turpentine. 4. A composition of matter for an adhesive, glue, or sizing, containing a proteid,

an alkaline earth hydroxid, a terpene liquid,

and sodium fiuorid.

'A composition of matter for an adhesive, glue, or sizing, containing a proteid,

an alkaline earth hydroxid, a terpeneliquid, sodium fluorid, and Portland cement.

6'..A composition of matter for an adhesive, glue, or sizing, containing by Weight a proteid substantially 100 parts; a terpene liquid substantially from i to g of 1 part, and alkaline earth hydroxid substantially 12 parts.

7. A composition of matter for an adhesive, glue, or sizing, containing by Weight casein substantially 100 parts, spirits of turpentine substantially from 1% to i} of 1 part, and lime substantially 12 parts.

8. A composition of matter for an, adhesive, glue, or sizing, containing by Weight casein substantially 100 parts, lime substantially 12 parts, sodium fluorid substantially 5 parts, and a terpene liquid substantially from i to g of 1 part.
